MMX Lowering Spring Kit For G42 BMW M240i RWD

MMX Performance Lowering Springs for the BMW M240i G42 (RWD) strike the ideal balance between sharper handling and a more aggressive stance — all without compromising ride comfort. With a drop of approximately 20mm at the front and 15mm at the rear, the G42 gains a more planted feel, offering improved responsiveness, lighter dynamics, and noticeably crisper turn-in.

The MMX Performance Lowering Spring Kit is one of our best-selling upgrades — and it’s easy to see why. Renowned for delivering the perfect blend of sharper handling, improved stance, and everyday comfort, it’s the ideal first mod for your BMW M240i G42.

Lowering the car’s centre of gravity — by approximately 20mm at the front and 15mm at the rear — makes a real difference to the way it drives. Body roll is noticeably reduced, turn-in feels sharper, and overall dynamics are greatly improved, all while retaining the comfort and refinement you’d expect from a BMW.

Thanks to carefully chosen progressive spring rates, low-speed ride quality remains smooth — in fact, it actually feels more composed around town. But push on, and the G42’s chassis really comes alive: it feels lighter on its feet, more direct, and properly responsive through the corners. Just what the M240i needed.

Visually, the difference is just as striking. The lower ride height gives the car a more aggressive, purposeful stance without being over-the-top.

Go any lower or firmer than these, and you risk upsetting the balance — with mismatched damping and limited spring travel leading to a crashy, unsettled ride. That’s why MMX Springs are engineered specifically to work in harmony with both static and Adaptive M dampers.
